Traffic Offloading Probability for Integrated LEO Satellite-Terrestrial Networks
Hossein Akhlaghpasand, Vahid Shah-Mansouri
In this paper, we consider traffic offloading of integrated low earth orbit (LEO) satellite-terrestrial network. We first derive traffic offloading probability from the terrestrial…
Design and Evaluation of Crowd-sourcing Platforms Based on Users Confidence Judgments
Samin Nili Ahmadabadi, Maryam Haghifam, Vahid Shah-Mansouri +1
Crowd-sourcing deals with solving problems by assigning them to a large number of non-experts called crowd using their spare time. In these systems, the final answer to the questio…
Delay Analysis of Base Station Flow Table in SDN-enabled Radio Access Networks
Seyed Hamed Rastegar, Aliazam Abbasfar, Vahid Shah-Mansouri
Future generation wireless networks are designed with extremely low delay requirements which makes even small contributed delays important. On the other hand, software defined netw…
Generative Adversarial Networks (GANs) in Networking: A Comprehensive Survey & Evaluation
Hojjat Navidan, Parisa Fard Moshiri, Mohammad Nabati +4
Despite the recency of their conception, Generative Adversarial Networks (GANs) constitute an extensively researched machine learning sub-field for the creation of synthetic data t…
